In this project study , the following three researches were carried out . Almost the studies were undertaken at the short period because considerable phenomena related to environmental change in Antarctic region were detected during the austral spring to summer . The observation , analyses of the date and materials , and discussion at workshops were timely performed and they produced lots of fruitful results .(1) Environmental change in atmosphere and magnetospherePlasma current in magnetosphere was surveyed using HF radar and imaging riometer as well as in mesosphere and thermosphere , and significance and importance of long-term observation in the aurora conjugating zone in the Arctic was confirmed .(2) Environmental change in atmo-hydrosphere and lithosphereData on the relationships between periglacial phenomena and Cenozoic era were comparatively analyzed . In order to establish the date of the rocks at the Sorrondane mountain region , the rock samples are analyzed by mass spectrometer (Ion microprobe) .(3) Marine environmental change in Southern OceanThe possibility of the middle- and long-term observation in the Indian sector in the Southern Ocean was surveyed and the date were analyzed . The present status of international collaborative study , and date bank and marine resources was surveyed .

在本项目研究中，主要进行了以下三个方面的研究。这些研究几乎都是在短期内进行的，因为在南方春季至夏季期间发现了与南极区域环境变化有关的许多现象。及时进行了数据和资料的观察、分析和研讨会讨论，取得了丰硕的成果。(1)大气和磁层的环境变化利用高频雷达和成像测速仪对磁层、中间层和热层的等离子体电流进行了观测，确认了北极极光共轭区长期观测的意义和重要性。(2)对比分析了大气-水圈和岩石圈的环境变化，冰周现象与新生代的关系。为了确定索伦丹山区岩石的年代，对岩石样品进行了质谱（离子探针）分析。(3)南大洋海洋环境变化调查了在南大洋印度洋海域中长期观测的可能性，并对观测数据进行了分析。综述了国际合作研究、数据库和海洋资源的现状。
